12. pecifications Schematic LED Indicators D D D O O0 O Overview Introduction Many important devices used in today s industrial environment are still designed for use with an RS 232 interface The reason is due in part to tradition and in part to convenience RS 232 hardware is relatively easy to design and the device can be readily connected to most PCs The drawback is that RS 232 is a point to point interface and it imposes a distance limitation of only 15 meters between the device and the computer To overcome these limitations many users employ RS 232 to RS 422 485 converters allowing RS 232 devices to connect to an industrial RS 422 or RS 485 network and transmit data over distances up to 1 2 km The RS 422 485 standards overcome the distance limitation by using a differential signal for transmitting data and control signals In addition to distance and multi drop issues for industrial applications housing wiring power supply and over surge protection are also serious concerns TCC 100I provides isolation protection for users who need an industrial grade interface conversion product to extend RS 232 transmission distance and increase networking capability Its superior industrial application design which includes DIN rail mounting terminal block wiring external terminal block power and optical isolation for system protection makes TCC 100I suitable for use in critical industrial environments Simply put your RS 232 de
